Today the file is moved in lib and not in lib/crypto...

change the comment or the file location.

compiled if CONFIG_FIT_SIGNATURE = y

but after used in mkimage even if CONFIG_FIT_SIGNATURE is not used...

(see after dumpimage-mkimage-objs)

it could be more simple to have :

obj-y += hash-checksum.o

or add a new config CONFIG_HASH (but we need to managed dependancy in Kconfig / Makefile)

lib/hash-checksum.o is required here...
